“…The soil moisture conserved with mulch was 4.5, 12.7 and 17.9 mm in IW/Pan-E ¼ 0.8, 0.6 and 0.4, respectively. Improvement in soil moisture storage and lowering of soil temperature with straw mulching is in agreement with the findings of Schonbeck and Evanylo (1998), Aulakh and Sur (1999), Agele et al (2000), Ossom et al (2003), and Sekhon et al (2005).…”

In northern India, chilli is transplanted in the hot and dry months of February and March when the crop depends upon irrigation water for canopy establishment. Hybrid chilli may require more irrigation water and fertilizer N due to its higher yield potential but the problem of the depleting groundwater table in the region necessitates developing a technique for reducing water requirement. Rice residue mulching can lower soil temperature and reduce evaporation losses from soil. An experiment was conducted on sandy loam soil for three years to evaluate the effect of rice straw mulch @ 6 Mg ha 71 on yield, fertilizer N and irrigation water requirement of hybrid chilli. Maximum and minimum soil temperatures at 50 mm depth during 2003 were lowered up to 8.9 and 2.28C, respectively, by rice residue mulching. Mulching improved fresh red chilli yield by 2.4 Mg ha 71 and required 120 mm less irrigation water. Substantial yield increase with mulching may be attributed to favourable soil hydrothermal regime as evident from lower soil temperature, higher profile moisture (12 mm) and 13.5 Mg ha 71 lower weed biomass. Chilli yield obtained with 45 kg N ha 71 with mulch was the same as that of 75 kg N ha 71 without mulch. Ascorbic acid content decreased with lower irrigation frequency but was significantly higher without mulch.

“…Gliricidia leaves gave the best result on increasing the ash content in the leaves. These results are supported by Ossom et al (2016) who reported that straw mulch was able to increase the nutritional content in sweet potato (Ipomoea batatas L.). Awopegba et al (2017) also reported that the application of Cajanus cayan and Chromolaena odorata mulch was able to increase ash content in corn.…”

“…Acacia and gliricidia probably also increase Ca content in the soil, as Mugwe et al (2017) stated that legume could increase Ca content in the soil. According to Mollah et al (2015), the organic fertilizer is a source of C-organic and Ca, and this is in line with the study done by Ossom et al (2016) who stated that the application of straw mulch was able to increase the Ca content in sweet potato (Ipomoea batatas L.).…”

A complete content of chemical substance from Aloe vera leaf makes this plant has many functions such as the ingredient of functional food for health, cosmetics, and herbal medicines. This research was aimed to determine the yield and quality of Aloe vera L. on various types and rates of green mulch in coastal sandy soil. The research was conducted in coastal sandy soil of Poncosari Srandakan, Bantul, Yogyakarta and done in a Randomized Complete Block Design (RCBD) of two factors with three replications. The first factor was four types of green mulch (shrimp evergreen, cashew, acasia and gliricidia). The second factor was various rate of green mulch consisted of three levels rates of leave mulch (5.0, 10.0, and 15.0 tons ha-1). Soil without mulching was used as a control treatment. The variables observed were yield at the first harvest time and leaf content quality which includes water, protein, fat, carbohydrate, ash, fiber, and mineral (Ca, Fe and Zn). The results showed that there was interaction between types and rates of leave mulch in all variables observed. Gliricidia leaf mulch gave the best effect with optimum rate about of 10 ton ha-1. The effectiveness of green mulch abilities on improving the observed variables from higher order to low was gliricidia, acasia, cashew and shrimp-type evergreen with the rate range between 10 up to 15 tons ha-1.

“…Layering or mulching the soil surface prevented weed seed germination and physically suppressed the seedling emergence. In another study by Ossom et al (2003), it was reported that white and green covering had petite effect on weeds, whereas brown, black, blue or white on black films significantly reduced emergence of weeds. Daisley et al (1988) also observed significant differences in weed control between mulched and unmulched plots of eggplant, cowpea and sweet potato.…”

Weed suppression through physical methods in cultivation constitutes of many methods but this experiment focused on application of various mulches. Recently, herbicide-free weed control methods in the world are getting more attention due to environmental and ecological factors. Green pepper production requires good management practices in order to attain potential yields. Most of the known physical practices of weed control cause both positive and negative effects. Therefore, great attention should be paid when selecting the appropriate mulch with the aim of weed suppression in any specific cultivation. Three types of mulches were examined for weed control namely; black plastic mulch, transparent plastic mulch, straw mulch and bare soil as control during the 2015 short and long raining seasons in Busia County. In both seasons, the black plastic mulch treatment significantly (P<0.05) showed the lowest number of weed species (3) per m 2 quadrat while the control had the highest with a maximum of 8 and 7 during the long and short raining seasons respectively. The number of species reduced after four weeks from transplanting when the first sampling was carried out. The lowest weed vigor was exhibited in the plastic treatments for both seasons at 4, 6 and 8 weeks after transplanting. Control had the highest weed fresh biomass for both seasons at all the sampling stages with the highest observed during the short raining season with 1626 g/m 2 at 4 weeks after transplanting. This also translated to the highest weed dry biomass for both seasons in the control plots with the lowest recorded in the black plastic mulch. Out of several physical methods of weed control, mulching seems to be the most appropriate with the black plastic mulch being the best.
